Description
Technical field
The present invention relates to technical field of building construction, and in particular to a kind of FRP wall reinforcement device and reinforcement means.
Background technique
Building leads to wall segment serious aging due to using the time long, so as to cause wall bearing capacity it is continuous under
Drop, there is more serious security risks.Therefore such wall need to be reinforced.However, the wall reinforcement of the prior art
Structure is reinforced primarily directed to the crack cracked, rather than is fundamentally reinforced to still uncracked wall.Separately
Outside, it is reinforced just for the crack cracked, is merely capable of that crack is avoided further to crack, and cannot fundamentally improve wall
The bending strength of body.
Such as the existing a large amount of masonry house in ancient city Nanjing, only the masonry building of Republic just has more than 200, is Nanjing
The important component of architectural culture remnants has important antique value, use value and scientific research value.It experienced nearly one
After the baptism of time in century, these the Republic of China build gradually aging, degrade；The transformation wantonly of owner and use unit to structure
These buildings are subject to significantly to damage；In addition building structure at that time does not consider requirements for fortification against earthquake, structure
Shock resistance is not able to satisfy existing earthquake resistant design code requirement substantially.Have to preferably protect with good these of reasonable development
Representative excellent architecture leaves Architectural Heritage abundant for descendant, it is necessary to reinforce to the Republic of China's masonry building.
Generally there are several types of extending section methods, steel-encasing strengthening method, mesh reinforced cement for traditional reinforced masonry wall method
Mortar method for strengthening, external post-tensioned prestressing method for strengthening, cementation method and gunite concrete method for strengthening etc., these methods although through
The practical engineering application for having spent some time has the advantages that certain.But landmark is different from general industry and civil buildings,
The characteristics of having itself and particularity.Outstanding landmark requires the original style and features for keeping building, must not tie to top
Structure is changed, or even does not allow to modify to former alien invasion, in order to avoid original style and features is destroyed, traditional reinforcement means base
Originally these harsh requirements are unable to reach.
FRP Strengthened Masonry Walls method increasingly mature in recent years has gradually come into the public visual field.Using FRP reinforcing masonry structure
Reinforcing of the technology due to being not only suitable for wall Local Cracking, the reinforcing being also applied in bearing capacity of wall body deficiency situation, therefore
Start the great attention for gradually having obtained engineering circles in recent years.
It is compared with traditional reinforcing mode, this new technology has advantageous advantage:
1. high-strength efficient: the ductility and bearing capacity of component can be increased substantially, improve the stress performance of structure.FRP material
Tensile strength is about 10 times of steel, and specific gravity but only has the 1/4 of steel.
2. good corrosion resistance and durability: the component reinforced can be made to resist the corrosion of various acid, alkali, salt, raising is built
Build the overall durability of object.It is not required to periodic maintenance after reinforcing, and can play a protective role to internal structure；With enough suitable
Answer the ability of temperature change；Outside FRP plus fireproof coating can also effectively prevent fires, and enhance structure to the suitable of severe external environment
Should be able to power, extend structural life-time.
3. fatigue durability: structure the effects of for often bearing dynamic load, cyclic load, variable load, it can after reinforcing
The anti-fatigue performance of structure entirety is effectively ensured.
4. keeping appearance: various for various structure shapes, node, beam, plate, columns etc. such as round, rectangle and Irregular Boundary Surfaces
Structure position, FRP material reinforce the original appearance and shape that can keep structure substantially, this advantage has landmark
Absolutely not alternative significance.Simultaneously as the characteristics of FRP material itself lightweight, every square meter weight gain is general after reinforcing
One kilogram is not exceeded, it is basic to can consider the self weight for not changing original structure, the shock resistance of original structure has also been effectively ensured in this way
It can will not weaken because self weight is increased
5. facilitating construction: scene can be cut randomly with needs as the case may be when using FRP sheet material, be not required to prepare complicated
Construction tool.Therefore FRP strengthening construction process has many advantages, such as that the period is short, effect is high, land occupation is few.Data show that pasting
FRP reinforcing is 4 times to 8 times of affixing steel plate reinforcement construction effect.Further, since FRP cloth is flexible material, so substantially can be with
Reach 100% effective application rate, even if being also easily processed very much bubble is locally present, corresponding acceptance criteria is to require
Effective application rate reaches 70%, therefore the quality and examination of construction can be effectively guaranteed.
6. overall economic efficiency is good.Although FRP sheet material price is more expensive, consumptive material is less when reinforcing, when construction
Between it is short, do not need large-scale equipment, one-time investment cost may not necessarily be more than traditional reinforcement means.If sight is seen long-range again
It is some, consider long-term benefit, FRP durability is preferable, and the later period hardly needs maintenance, and long-term needed for other reinforcement means
Maintenance cost is higher.Therefore comprehensively consider, FRP method for strengthening seems more economical.

Degree is close to zero, and it is too high to replace mortar cost and working hour, so under the premise of being changed without mortar, by FRP material bonding partially
Its ultimate bearing capacity cannot be improved well on the metope of ancient building, but FRP material can not be pasted onto wall completely
On face, so burr 1a is arranged in the one side that FRP material is bonded with wall, at its back side of position that reinforcing layer 1 and column 2 contact
It is completely coated with glue, and its back side of position that reinforcing layer 1 is not contacted with column 2 is only coated with glue on burr 1a, thus by one
A whole metope is separated into several small metopes, bonding partially is carried out for each small metope, thus improving ancient architecture
Its structure ductility is improved while the ultimate bearing capacity of walling face.
Burr 1a is the honeycomb shape for being abound with the regular hexagon on 1 surface of reinforcing layer and being combined into.
Honeycomb shape is the firmest structure in the Nature, and when deformation of wall can pass through the active force of reinforcing layer 1
The burr 1a of honeycomb shape is evenly distributed in the surface of reinforcing layer 1, avoids generating stress concentration.
It is offered on wall for the through-hole that connecting rod 3 passes through between wallboard, the aperture of the through-hole is greater than connecting rod 3 between wallboard
Outer diameter is filled with anchoring adhesive in the gap between wallboard between connecting rod 3 and the through-hole.
